After you assemble the footage for your video, you need to match the music with your footage. Be sure to save your work before adding the music. If you don't and you make a mistake while working with the music, you will have to start all over again from scratch. After you save your assembled footage, import the music you want for your project into your project. For movie editing software, the music usually needs to be an MP3 file.

In Windows Movie Maker, you use the "Import audio or music" option that appears on the left below the Capture Video main item. Select the MP3 file or files you want to include with the video track. You drag the MP3 down to the audio / music bar in the timeline area; this is found beneath the video track area. If you are using a movie editing software package besides Windows Movie Maker, be sure to consult your manual or instructions on how to import the music into your project.

After you import your song or songs you want for your project, work at synchronizing the video and audio together. When you're matching the audio and video, be sure to work at synchronizing the emotions and the beat of the music with your assembled footage. You want to get the movements in the video you have assembled to look good with the audio, so it's usually best to have the characters move with the flow of the music. When the audio is strong, the character's movement should be powerful, and when the audio is soft, the character's movement should be subtle.

When you're synchronizing the video and audio, it's better to go with the feeling of the music and the lyrics, rather than trying to make literal matches between the footage and the lyrics (for example, using footage of someone crying every time the lyrics of a song mention crying or tears). Overall, the more you match the footage with the feeling and emotion of the song, viewers will probably be more willing to watch your anime music video more than one time.

You need to have a lot of patience when synchronizing the video and audio, because you'll want to take your time to make the best video that you can. After you are content with the flow of your music video, it's time to work at finalizing your project.
